 Source checkpoint on `codex/analysis-mixed-index-956atf-20260924`, based on
 `aaec78fcc9b273d1485497126392afdd1fb2e54e`. This records implemented structure;
 compilation and runtime acceptance have not yet occurred at this checkpoint.
+The first Windows strict core all-target Clippy attempt at `a18b7966` returned
+101 for the test's `6 | 7 | 8` pattern (`manual_range_patterns`); all 545 source
+inputs remained unchanged. Its receipt/log are preserved. The successor uses
+`6..=8` with the same cases and no production change. No test body ran in that
+attempt; corrected strict and runtime gates are still required.
 The accepted contract/review are published at
